Fishnder 350C Owner’s Manual 9
This is the temperature offset. Enter this value as a positive number if the
sensor connected to the shnder measures the water temperature as being
colder than it actually is. Enter this value as a negative number if the sensor
connected to the shnder measures the water temperature as being warmer
than it actually is.
4
Select MENU > Setup > Calibration > Temperature Offset.
5
Use and to select positive (+) or negative (-), based on the value
calculated in step 3.
6
Enter the value of the alarm setting.
7
Select ENTER.
8
Check the temperature offset value to ensure you have entered the correct
value.
Calibrating the Water Speed Sensor
1
Select MENU > Setup > Calibration > Calibrate Water Speed.
2

Specication Measurement
Temperature Range From 5°F to 131°F (from -15°C to 55°C)
Power Source Voltage Range 8–28 Vdc
Rated Current 1 A
Fuse AGC/3AG - 3.0 A
Freshwater Depth* 1500 ft. (457 m)
Saltwater Depth* 600 ft. (183 m)
* Depth capacity is dependent on water salinity, bottom type, and other water
conditions.
The included transducer has beam angles of 15 and 45 degrees at 3 dB. However,
when this transducer is used with the shnder device, it can detect the smallest
signals up to 60 and 120 degrees. Shallow and deep water performance is
maximized when this transducer and this shnder are used together because the
shnder shows more sh in shallower water, and it shows more details in deeper
water, such as structures and water bottom contours.
Cleaning the Outer Casing
NOTICE
Avoid chemical cleaners and solvents that can damage plastic components.
1
Clean the outer casing (not the screen) of the device using a cloth dampened
with a mild detergent solution.
2
Wipe the device dry.
